Patented Oct. 29, 1929 UNITED STATES WELLS S. FLEMING, OF PORTLAND,OREGON SURFACE DRAIN Application filed July 22,

This invention relates to improvements in floor drain fittings forshower baths and the like.

The object of my invention is the provision of a floor drain of simpleand practical construction which is adjustable for installation infloors of various thicknesses and to which a sheet of waterproofingmaterial may be connected in watertight condition without the employmentof bolts or screws to make a waterproof joint to prevent the leakage ofwater past the fitting and thereby protect the walls and ceilings inrooms below in the building from damage.

Other objects and advantages of my invention, and objects relating todetails of construction and arrangement of parts, will be readilyapparent in the course of the detailed description to follow.

The accompanying drawings illustrate, by way of example, one form inwhich my invention be embodied, wherein:

Fig. 1 is a vertical section of the floor drain embodying my inventionand set up in operative position; the section being taken on the line-1-1 of Fig. 2.

Fig. 2 is a horizontal section of the same on line 22 of Fig. 1.

Referring to said views, the reference 3 numeral 1 indicates thecylindrical body of my improved floor drain having a bore 2 extendingvertically therethrough. Said bore is provided with screw-threads 3 withwhich the end of a waste or drain pipe, not shown,

may be connected. At its upper end said bore is counterbored andprovided with screwthreads, as at 5.

A circular flange 6 extends in substantially horizontal directions witha relatively slight upward angle to afford drainage toward the bore 2,said flange being recessed at its upper face, as at 7.

A sheet of waterproofing material 8, such as sheet lead or tarred paper,apertured about the bore 2, is laid upon said flange and is clampedthereon in watertight condition by means of an annular spider-plate 10bearing upon said waterproof material adjacent the outer edge of saidrecess, as will be more fully explained hereafter.

1926. Serial No. 124,186.

Said spider-plate is provided with a plurality of evenly spaced integralarms 11 extending upwardly and inwardly and integrally connected to anannular collar 12 whose central opening is disposed in substantiallyvertical alignment with the counterbore 5 of the body.

A tubular hub 13 extends axially through the central opening of thecollar 12 and is screw-threaded at its lower extremity to engage thescrew-threads of the counterbore 5 and has its inner tubular face 15 insubstantial alignment with the bore 2. Said hub is formed with a headhaving a circular portion 16 arranged to bear upon the collar 12 of thespider-plate and an hexagonal upward portion 17 adapted to receive awrench. The interior tubular surface of said hub is provided withscrew-threads 18 at its upper portion, and therebelow the hub is formedwith a plurality of vertically enlongated slots 20 in spaced relationabout its circumference which are positioned to extend from a littlebelow the plane of the recess 7 upwardly therefrom to a point adjacentthe screw-threads 18.

A drain section 21 includes a tubular portion 22 and a funnel shapedupper end 23. The tubular portion 22 is provided with externalscrew-threads interfitting with the screw-threads 18 of the hub, wherebythe drain section may be adjusted to the desired elevation. The upperend of the funnel portion 23 is provided with a grille-plate 25 designedto be adjusted to the level of the floor in which the fitting is set.

To insure that the spider-plate 10 will not move in rotary directionswhen the hub portion 16 is screwed down thereupon, I provide an aperture26 in said spider-plate within which an integral stud 2?, extendingupwardly from the flange 6, protrudes.

The drain body 1 is set upon the subfloor 28 of the building in whichthe fitting is installed, and the waterproof sheet 8 is laid over theflange 6 as described. The spiderplate 10 is then positioned thereover,and the tubular hub 13 is extended into the counterbore 5 of the boreand the screw-threads thereon engaged to bring the head portion 16 tobear with pressure upon the collar 12, which pressure will becommunicated to the plate 10 and clamp the waterproof sheet firmly uponthe flange 6 in Watertight condition.

The drain section 21 may then be inserted within the tubular hub andadjusted to the height to which the superficial floor 30 is to beleveled. Said floor 30 may be composed of plastic or other suitablematerial and overlie and enclose the parts of the drain fitting inpermanent condition.

Having described my invention, whatI' claim, is: I
